One real-VM test mirroring thebeast's topology: OS disk + two data disks
addressed by /dev/disk/by-id/ (virtio serials standing in for NVMe
serials). Fresh k8s-worker v2 install must put labelled whole-disk xfs
on each data disk and drop the matching LVs; a flagless reprovision must
rediscover both by label and remount them unformatted -- proven by
marker files AND unchanged filesystem UUIDs.
Harness: createPxeVm grows dataDisks (extra virtio disks with fixed
serials, <=20 chars or the guest by-id link truncates), provisionVm
passes the by-id paths to /api/install, virtioById exported.
